Abstract

The invention can be used in printing, multicolor screen printing. The essence of the invention: when applying ink layers successively to the material to be printed, the second and subsequent ink layers are applied through an anti-marking mesh of appropriate thickness placed between the printing form and the material to be printed. 4 il.

Description

FIELD OF THE INVENTION The invention relates to printing, in particular to multi-color screen printing methods.

The purpose of the invention is to increase productivity.

Figure 1 shows the process of applying the first ink layer; Fin.2 - the same, the second layer of paint; on fig.Z - the same. the third layer of paint; figure 4 - print multicolor screen printing on the raw.

The drawing shows the printed material 1, the stencil printing plate 2 for the first ink, the stencil printing plate 3 for the second ink, the screen printing plate 4 for the third ink, the squeegee 5, the first ink and the ink layer 6, the second ink and the ink layer 7, a third paint and paint layer 8, an anti-marking sheet 9 for a second paint, an anti-marking grid 10 for a third paint.

The method is carried out as follows.

Through the screen printing plate 2 for the first ink (figure 1), the image of the printed material 1 is applied by the squeegee 5 with the image of the first ink layer 6. Then through the screen printing plate 3 for the second ink (figure 2) and the anti-label screen 9 on the printed material 1, containing a dry layer of the first ink 6, the doctor squeegee 5 draws the image of the second ink layer 7. At the same time, the anti-cutting mesh 9, whose thickness is equal to the thickness of the stencil mold 2, and therefore greater than or equal to the thickness of the first ink layer 6, reinforces it and rescues stencil screen printing plates from spreading with gaps 3. Next, through a stencil printing plate 4 for the third ink (Fig. 3) and an anti-label mesh 10 on the printed material 1 containing the colorful layers of the first and second ink, the third ink is applied by the squeegee 5 Layer 8 Anti-label mesh 10 prevents the paint layers of the first 6 and second 7 colors from spreading out. Similar paint layers are applied next. The result is a multi-color screen printing (figure 4), containing the dry layers of paint.

This method of multi-color screen printing is more productive and less energy-intensive, as it allows to obtain multi-color images without intermediate drying of individual paint layers.

Claims (1)

The invention of the method of multi-color screen printing, which consists in sequential application to the printed material Ink layers through appropriate stencil printing plates, characterized in that, in order to increase productivity, the second and subsequent ink layers are applied to a dry layer of the previous ink through an anti-gauge mesh of appropriate thickness located between the printing form and the material to be printed.
